Abstract

The invention discloses a roadbed detection sampler which comprises a drill, wherein a bump is arranged on the outer side of the drill; a rotary shaft is arranged on the top of the drill; a thread isarranged on the outer surface of the rotary shaft; a bearing is arranged in the bottom of the rotary shaft; a motor is arranged on the top of the bearing; a motor room is arranged on the outer side ofthe motor; slide blocks are arranged on two sides of the motor room; a baffle plate is arranged in the bottom of the drill; fixed blocks are arranged on two sides of the baffle plate; brackets are arranged on the outer sides of the fixed blocks; two buffer seats are arranged in the bottom of an inner cavity of each bracket; a buffer rod is arranged between the two buffer seats; a buffer spring isarranged on the outer side of the buffer rod; and a chute is formed in the top of the inner wall of each bracket. By arranging a shock absorbing device and the easily mounted drill, the service lifeof the machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of highway subgrade detection, in particular to a subgrade detection and sampling machine. Background technique [0002] Subgrade refers to the belt-shaped structure used as the foundation of the road surface according to the location of the route and certain technical requirements. It is constructed with soil or stone. The subgrade is often affected by rain and climate, and its resistance is poor. In road construction, the detection of subgrade quality is essential. The drilling tool design of the commonly used drilling sampling machine is very complicated and difficult to maintain. [0003] Most of the machines used in big cities are very complex and expensive machines. These expensive machines are not acceptable to everyone. In rural areas, relatively simple machines are used. Because the roads in rural areas are relatively potholed, The drill bit used must be selected according to the area of ​​use, oth...
